Title: Turbomachine
Inventor: GUPTA RAJENDRA P
IPC: F04D29/38
Filed: 2000-09-11
Abstract: La présente invention concerne une turbomachine comprenant un rotor (10) muni d'une ou plusieurs bulles (12) semblables à des godets de ramassage aux extrémités ouvertes dans le disque du rotor.  Le rotor (10) est placé dans une enveloppe.  Dans le cas d'un compresseur, le rotor est entraîné par le courant et lorsqu'il tourne, l'action de ramassage des godets crée un écoulement fluidique à travers le rotor.  Dans une configuration de groupe motopropulseur, l'écoulement fluidique à grande vitesse entraîne le rotor (10) et l'énergie est générée sur son arbre.  Dans un autre mode de réalisation, l'enveloppe comprend aussi un stator.  Le stator est également muni d'un ou plusieurs godets d'entrée et de sortie qui permettent de produire les écoulements fluidiques désirés à travers le stator.  Dans d'autres modes de réalisation, l'invention concerne des turbomachines à plusieurs étages dans lesquelles un ou plusieurs rotors (10) et stators sont placés alternativement dans l'enveloppe qui est sensiblement symétrique sur le plan axial.

Title: Collapsible display carrier and method of making
Inventor: CARVER ROBERT G
IPC: B65D71/00
Filed: 1989-10-31
Abstract: Abstract of the Disclosure A display carrier for glassware or the like is foldable from a generally flat, collapsed condition for shipping and storage to an erect position for retaining at least a pair of articles.  The carrier is formed of a flexible material which forms a top wall, a bottom wall and a pair of side walls, each side wall being hinged to each of the top and bottom walls to form a carrier sleeve.  A reinforcing wall extends between the top and bottom walls.  Planar retaining tabs are resiliently connected along a foldline of the top and bottom walls, and each tab is contoured to match a part of the surface of the article to be carried.  Bights in the reinforcing wall limit movement of the retaining tabs.  When the carrier is folded flat, the reinforcing wall holds the tabs flat against the top and bottom walls to which they are hinged.  The carrier may also include a lift tab which lifts the retaining tabs from the flat position against the top and bottom walls to a position in which they bear against a respective bight.  The method of making the carrier from a blank is also disclosed.

Abstract: The present invention provides an apparatus for anchoring of equipment within the interior bore of a section of a subterranean well conduit, and particularly for insertion of such equipment.  The apparatus comprises a cylindrical housing and a conically tapered surface around the exterior of the housing which is radially larger at its upper end and tapered to a radially smaller lower end.  A seal body is provided which is carried exteriorly around the housing and has its interior tapered end reverse to that of the conically tapered surface around the housing and which is selectively longitudinally movable relative to the housing from a first, unset position on the conduit section to a second, set position on the conduit section and radially expandable during the movement relative to the housing.  Anchoring means are carried exteriorly around the body for securing the apparatus to the conduit section against upward and downward movement of the apparatus.  A bi-directional anchoring system is provided such that force received on or through either end of the apparatus drives the apparatus into further anchoring engagement with the conduit section.  A metal-to-metal primary and elastomeric secondary seal system are provided on the apparatus with the secondary elastomeric seal having zero extrusion and slip body having a ductility of from between about 1% and about 15%.

Title: Sound imaging apparatus for a video game system
Inventor: LOWE DANNY D
IPC: H04S7/00
Filed: 1990-12-06
Abstract: ABSTRACT OF THE DISCLOSURE   SUMMARY OF THE INVENTION         The game software (10) for a video game system includes sound positioning information that utilizes two spaced-apart speakers (26, 28) to give the player the impression that the sound is emanating from a location other than the actual speaker locations, for example, to the far right or the far left of the speakers.  A sound processor (220) operates upon monaural signals from an audio synthesizer (180) in response to the sound positioning information from the game software (10) so that each monaural signal from the audio synthesizer is divided into two signals and at least one of the signals is passed through a transfer function to produce two-channel output signals that have a differential phase and amplitude relationship therebetween that is adjusted on a frequency dependent basis.  Each different sound location generally requires a  specific different relationship, and the sound processor for the video game may include a number of different transfer functions, each of which can be embodied by adjusting a digital filter (60) in response to the sound positioning information.  Each digital filter (60) alters the amplitude and phase of the applied signal in a frequency dependent manner over the audio frequency spectrum.
